Issue Database - Filsystem mismatch

[marrog86]

Hello,

I found an issue I caused myself somehow during workiing woth Proxymanager.

In the log file, I consistently saw the message: "conflicting server name ******* on [::]:80, ignored." Even after deleting all configurations for this subdomain in the web UI, the message persisted, and Certbot frequently failed.

The root cause was a lingering 1.conf configuration file in redirection_host from an earlier attempt, despite there being no redirection configured in the UI.

To prevent this for other users, I suggest implementing a check to clear configuration files that exist on the filesystem but are no longer present in the database.
